Newbie needs help EML light Lack of Turbo boost
Right im new here guys so go easy wid all the technical terms i just bought my first WRX today on a 52 plate and have a slight problem (already)...
The car is generaly in mint condition inside and out not a mark to be seen and has covered 48k with a full service history.
Its completely standard apart from a dump valve!
After parting with a tidy sum of money on the return journey home after exiting a roundabout at a reasonable speed (as ya do with a new motor to see what its like), the EML light decided to light up and stay on constanly (that being the one above the temp guage, not sure if there's another).
Since then there is a distinct lack of boost from the turbo it's trying to go but seems to be holding back a bit like a flat spot if you will.
If i depress the accelerator really gently and ease it on it seems to go a little better but if i simply put my foot flat to the floor it doesn't. Very occasionaly it will lift of and go like stink but as soon as i change gear its back to the flat spot again!
Any ideas what this could be any help would be greatly appreciated
Ps i filled it with super unleaded too

Just been into town to pick the wife up and tried to give it some beans and it did try and go with a bit of throttle tickleing but when the pedal gets to about mid way it seems to die then if i floor it it tries to go almost like a misfire but not if that makes any sense...

i would check all the hoses on the boost side and inlet tract> one probably come off or split> even the small ones boost soloniod/actuator etc> its sounds like its taking in air that the maf isnt measuring
